Yonago in context
The chart above shows SNDi trends for new street additions (left panel) and the entire network (right panel), with Yonago plotted against Tottori and Japan. All three follow the same trend in new construction, suggesting a shared regional pattern of development.

In new street additions, Yonago fluctuated in its street-construction patterns, while Dholka built increasingly disconnected streets from 1975 through 1976-1990, then improved and Arambagh built increasingly disconnected streets over time. Looking at the full network, Dholka and Arambagh both became progressively more disconnected, while Yonago fluctuated in connectivity. Notably, Yonago had a more sprawly network than Arambagh in 1975 but the two have since reversed their relative ranking.
